FIG. 1 shows an IPTV system 100 including a client facing tier 102, an application tier 104, an acquisition tier 106, and an operations and management tier 108. Each tier 102, 104, 106, and 108 is coupled to one or both of a private network 110 and a public network 112. For example, the client-facing tier 102 can be coupled to the private network 110, while the application tier 104 can be coupled to the private network 110 and to the public network 112 such as the Internet. The acquisition tier 106 can also be coupled to the private network 110 and to the public network 112. Moreover, the operations and management tier 108 can be coupled to the public network 112.

The various tiers 102, 104, 106 and 108 communicate with each other via the private network 110 and the public network 112. For instance, the client-facing tier 102 can communicate with the application tier 104 and the acquisition tier 106 via the private network 110. The application tier 104 can also communicate with the acquisition tier 106 via the private network 110. Further, the application tier 104 can communicate with the acquisition tier 106 and the operations and management tier 108 via the public network 112. Moreover, the acquisition tier 106 can communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, elements of the application tier 104 can communicate directly with the client-facing tier 102.

The client-facing tier 102 can communicate with user equipment via a private access network 166, such as an Internet Protocol Television (IPTV) network. In an illustrative embodiment, modems such as a first modem 114 and a second modem 122 can be coupled to the private access network 166. The client-facing tier 102 can communicate with a first representative set-top box device 116 via the first modem 114 and with a second representative set-top box device 124 via the second modem 122. The client-facing tier 102 can communicate with a large number of set-top boxes over a wide geographic area, such as a regional area, a metropolitan area, a viewing area, or any other suitable geographic area that can be supported by networking the client-facing tier 102 to numerous set-top box devices. In one embodiment, the client-facing tier 102 can be coupled to the modems 114 and 122 via fiber optic cables. Alternatively, the modems 114 and 122 can be digital subscriber line (DSL) modems that are coupled to one or more network nodes via twisted pairs, and the client-facing tier 102 can be coupled to the network nodes via fiber-optic cables. The set-top box devices 116 and 124 can process data received from the private access network 166 via an IPTV software platform such as Microsoft™ TV IPTV Edition.

The first set-top box device 116 can be coupled to a first display device 118, such as a first television monitor, and the second set-top box device 124 can be coupled to a second display device 126, such as a second television monitor. Moreover, the first set-top box device 116 can communicate with a first remote control 120, and the second set-top box device 124 can communicate with a second remote control 128. In an exemplary, non-limiting embodiment, each set-top box device 116 and 124 can receive data or video from the client-facing tier 102 via the private access network 166 and render or display the data or video at the display device 118 or 126 to which it is coupled. The set-top box devices 116 and 124 thus may include tuners that receive and decode television programming information for transmission to the display devices 118 and 126. Further, the set-top box devices 116 and 124 can include a set-top box processor 170 and a set-top box memory device 172 that is accessible to the set-top box processor. In a particular embodiment, the set-top box devices 116 and 124 can also communicate commands received from the remote controls 120 and 128 back to the client-facing tier 102 via the private access network 166.

In an illustrative embodiment, the client-facing tier 102 can include a client-facing tier (CFT) switch 130 that manages communication between the client-facing tier 102 and the private access network 166 and between the client-facing tier 102 and the private network 110. As shown, the CFT switch 130 is coupled to one or more data servers 132 that store data transmitted in response to user requests, such as video-on-demand material. The CFT switch 130 can also be coupled to a terminal server 134 that provides terminal devices, such as a game application server and other devices with a common connection point to the private network 110. In a particular embodiment, the CFT switch 130 can also be coupled to a video-on-demand (VoD) server 136.

The application tier 104 can communicate with both the private network 110 and the public network 112. In this embodiment, the application tier 104 can include a first application tier (APP) switch 138 and a second APP switch 140. In a particular embodiment, the first. APP switch 138 can be coupled to the second APP switch 140. The first APP switch 138 can be coupled to an application server 142 and to an OSS/BSS gateway 144. The application server 142 provides applications to the set-top box devices 116 and 124 via the private access network 166, so the set-top box devices 116 and 124 can provide functions such as display, messaging, processing of IPTV data and VoD material. In a particular embodiment, the OSS/BSS gateway 144 includes operation systems and support (OSS) data, as well as billing systems and support (BSS) data.

The second APP switch 140 can be coupled to a domain controller 146 that provides web access, for example, to users via the public network 112. The second APP switch 140 can be coupled to a subscriber and system store 148 that includes account information, such as account information that is associated with users who access the system 100 via the private network 110 or the public network 112. In a particular embodiment, the application tier 104 can also include a client gateway 150 that communicates data directly to the client-facing tier 102. In this embodiment, the client gateway 150 can be coupled directly to the CFT switch 130. The client gateway 150 can provide user access to the private network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116 and 124 can access the system via the private access network 166 using information received from the client gateway 150. The private access network 166 provides security for the private network 110. User devices can access the client gateway 150 via the private access network 166, and the client gateway 150 can allow such devices to access the private network 110 once the devices are authenticated or verified. Similarly, the client gateway 150 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices, from accessing the private network 110 by denying access to these devices beyond the private access network 166.

For example, when the first set-top box device 116 accesses the system 100 via the private access network 166, the client gateway 150 can verify subscriber information by communicating with the subscriber and system store 148 via the private network 110, the first APP switch 138 and the second APP switch 140. Further, the client gateway 150 can verify billing information and status by communicating with the OSS/BSS gateway 144 via the private network 110 and the first APP switch 138. The OSS/BSS gateway 144 can transmit a query across the first APP switch 138, to the second APP switch 140, and the second APP switch 140 can communicate the query across the public network 112 to the OSS/BSS server 164. After the client gateway 150 confirms subscriber and/or billing information, the client gateway 150 can allow the first set-top box device 116 access to IPTV content and VoD content. If the client gateway 150 cannot verify subscriber information for the first set-top box device 116, such as because it is connected to a different twisted pair, the client gateway 150 can deny transmissions to and from the first set-top box device 116 beyond the private access network 166.

The acquisition tier 106 includes an acquisition tier (AQT) switch 152 that communicates with the private network 110. The AQT switch 152 can also communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, the AQT switch 152 can be coupled to a live acquisition server 154 that receives television content, for example, from a broadcast service 156. Further, the AQT switch can be coupled to a video-on-demand importer server 158 that stores television content received at the acquisition tier 106 and communicate the stored content to the client-facing tier 102 via the private network 110.

The operations and management tier 108 can include an operations and management tier (OMT) switch 160 that conducts communication between the operations and management tier 108 and the public network 112. In the illustrated embodiment, the OMT switch 160 is coupled to a TV2 server 162. Additionally, the OMT switch 160 can be coupled to an OSS/BSS server 164 and to a simple network management protocol (SNMP) monitor 167 that monitors network devices. In a particular embodiment, the OMT switch 160 can communicate with the AQT switch 152 via the public network 112.

In a particular embodiment during operation of the IPTV system, the live acquisition server 154 can acquire television content from the broadcast service 156. The live acquisition server 154 in turn can transmit the television content to the AQT switch 152 and the AQT switch can transmit the television content to the CFT switch 130 via the private network 110. Further, the television content can be encoded at the D-servers 132, and the CFT switch 130 can communicate the television content to the modems 114 and 122 via the private access network 166. The set-top box devices 116 and 124 can receive the television content from the modems 114 and 122, decode the television content, and transmit the content to the display devices 118 and 126 according to commands from the remote control devices 120 and 128.

Additionally, at the acquisition tier 106, the VoD importer server 158 can receive content from one or more VoD sources outside the IPTV system 100, such as movie studios and programmers of non-live content. The VoD importer server 158 can transmit the VoD content to the AQT switch 152, and the AQT switch 152 in turn can communicate the material to the CFT switch 130 via the private network 110. The VoD content can be stored at one or more servers, such as the VoD server 136.

When a user issues a request for VoD content to the set-top box device 116 or 124, the request can be transmitted over the private access network 166 to the VoD server 136 via the CFT switch 130. Upon receiving such a request, the VoD server 136 can retrieve requested VoD content and transmit the content to the first set-top box device 116 or to the second set-top box device 124 across the private access network 166 via the CFT switch 130. In an illustrative embodiment, the live acquisition server 154 can transmit the television content to the AQT switch 152, and the AQT switch 152 in turn can transmit the television content to the OMT switch 160 via the public network 112. In this embodiment, the OMT switch 160 can transmit the television content to the TV2 server 162 for display to users accessing the user interface at the TV2 server. For example, a user can access the TV2 server 162 using a personal computer (PC) 168 coupled to the public network 112.

The domain controller 146 communicates with the public network 112 via the second APP switch 140. Additionally, the domain controller 146 can communicate via the public network 112 with the PC 168. For example, the domain controller 146 can display a web portal via the public network 112 and allow users to access the web portal using the PC 168. Further, in an illustrative embodiment, the domain controller 146 can communicate with at least one wireless network access point 178 over a data network 176. In this embodiment, each wireless network access device 178 can communicate with user wireless devices such as a cellular telephone 184.

In a particular embodiment, set-top box devices 116 and 124 can include a set-top box computer program 174 that is embedded within the set-top box memory device 172. The set-top box computer program 174 can contain instructions to receive and execute at least one user television viewing preference that a user has entered by accessing an Internet user account via the domain controller 146. For example, the user can use the PC 168 to access a web portal maintained by the domain controller 146 via the Internet. The domain controller 146 can query the subscriber and system store 148 via the private network 110 for account information associated with the user. In a particular embodiment, the account information can associate the user's Internet account with the second set-top box device 124. For instance, in an illustrative embodiment, the account information can relate the user's account to the second set-top box device 124 by associating the user account with an IP address of the second set-top box device, with data relating to one or more twisted pairs connected with the second set-top box device, with data related to one or more fiber optic cables connected with the second set-top box device, with an alphanumeric identifier of the second set-top box device, with any other data that is suitable for associating the second set-top box device with a user account, or with any combination of these.

The set-top box computer program 174 can contain instructions to receive many types of user preferences from the domain controller 146 via the access network 166. For example, the set-top box computer program 174 can include instructions to receive a request to record at least one television program at a video content storage module such as a digital video recorder (DVR) 182 within the second set-top box device 124. In this example embodiment, the set-top box computer program 174 can include instructions to transmit the request to the DVR 182, where the television program(s) are recorded. In an illustrative embodiment, the set-top box computer program 174 can include instructions to receive from the DVR 182 a recording status with respect to one or more of the television programs and to transmit at least one message regarding the status to a wireless device, such as the cellular telephone 184. The message can be received at the CFT switch 130, for instance, and communicated to the domain controller 146 across the private network 110 via the second APP switch 140. Further, the domain controller 146 can transmit the message to the wireless data network 176, directly or via the public network 112, and on to the wireless network access point 178. The message can then be transmitted to the cellular telephone 184. In an illustrative embodiment, the status can be sent via a wireless access protocol (WAP).

Further details of the remote control device 128 are described in U.S. patent application Ser. No. 11/847,120, the disclosure of which is hereby incorporated by reference.

FIG. 3 shows a block diagram of a number of components in the remote control device 128 including a two-way audio transceiver 380, a processor 382, a digital audio storage 384, and a LED display 386. The microphone 266 is coupled to the digital audio storage 384 through the processor 382. The LED annulus 268 is coupled to the talk button 270 and the two-way audio transceiver 380. The talk button 270 is coupled to the two-way audio transceiver 380 and the digital audio storage 384. The optical distance measurer 272 is coupled to the two-way audio transceiver 380. The speaker 274 is coupled to the two-way audio transceiver 380. The audio output 276 is coupled to the two-way audio transceiver 380. The IR transmitter 278 is in communication with the processor 382. The two-way audio transceiver 380 is in communication with the processor 382. The digital audio storage 384 is in communication with the processor 382. The LED display 386 is in communication with the processor 382.

The microphone 266 can be used to receive an audio input from the user of the remote control device 128. Upon the talk button 270 being pressed, the remote control device can transmit the audio input to the second set-top box device 124. The LED annulus 268 can light-up, indicating that the talk button 270 has been pressed and the remote control device 128 is transmitting the audio input to the second set-top box device 124. The optical distance measurer 272 can determine a distance that the user is from the remote control device 128, such as by transmitting a reflective optical beam from the remote control device. The speaker 274 can output a digital audio signal received by the remote control device 128 from the second set-top box device 124. The audio output 276 can output, to an external audio device (not shown), the digital audio signal received by the remote control device 128 from the second set-top box device 124. The IR transmitter 278 can transmit IR control signals to the auxiliary devices. The IR control signals can be used to perform various functions on any of the auxiliary devices, such as changing the channel, changing the volume level, and the like on the second set-top box 124.

Whenever any button is pressed on the remote control device 128, such as channel up/down buttons 256 of FIG. 2 , the digital audio storage 384 activates and records an audio input received at the microphone 266. The audio input is stored in a local audio circular buffer of the digital audio storage 384 for a predetermined amount of time. The predetermined amount of time can be any length of time, for example five seconds. Additionally, upon a button being pressed on the remote control device 128, the two-way audio transceiver 380 activates such that the audio input can be transmitted to the second set-top box device 124. The two-way audio transceiver 380 can alternatively be placed in a sleep mode to conserve battery life if no button is pressed for a predetermined period, such as fifteen seconds. Upon the talk button 270 being pressed, the remote control device 128 can execute a number of functions at substantially the same time. The remote control device 128 can set the recording mode to “start,” light-up the LED annulus 268, activate the audio digital storage 384, activate the two-way audio transceiver 380, and trigger the optical distance measurer 272 to determine a distance between the remote control device 128 and the user's face.

When the recording mode is set to “start,” the remote control device 128 can send the last audio input stored in the local audio circular buffer of the digital audio storage 384 to the second set-top box device 124. At substantially the same time, the remote control device 128 can send a control parameter embedded in a radio frequency (RF) control signal to the second set-top box device 124. The control parameter can contain the distance measurement determined by the optical distance measurer 272, such as four and one-half inches. Based on the control parameter associated with the distance measurement received from the remote control device 128, the second set-top box device 124 can automatically adjust level of audio amplification for the audio input received. The adjustment level of the audio amplification can compensate for a variability that the user's mouth is too far away from the microphone 266 or too close to it. Finally, the remote control device can change the recording mode to “on.”

When the recording mode is “on,” the microphone 266 can continue to receive the audio input and the two-way audio transceiver 380 can send it as a digital audio stream to the second set-top box device 124. Upon receiving the digital audio stream, the second set-top box device 124 can stream the digitized audio packets to the multimedia application server 142 over the private network 110 of FIG. 1 . The multimedia application server 142 can process the speech input and/or pass it in real time to a voice search engine, where the audio input can be used to perform a voice search for a specific television program. Upon receiving the end of the audio input, the multimedia application server 142 can send a control message to the second set-top box device 124 indicating the end of a speech input session.

Upon receiving the end of speech input from multimedia application server 142, the second set-top box device 124 can present a visual icon on the display device 126 of FIG. 1 , such as displaying a muted microphone icon, indicating that the end of the speech input is reached. At substantially the same time, the second set-top box device 124 can send an RF control signal to the remote control device 128 indicating the end of the speech input. Upon receiving the RF control signal from the second set-top box device 124, the remote control device 128 can change the recording mode from “on” to “off.” Additionally, the remote control device 128 can set the recording mode to “off” if a predetermined amount of time, such as two seconds, elapses after talk button 270 has been released and the audio input level is below a predetermined level. When the recording mode is changed from “on” to “off,” the remote control device 128 can turn off the LED annulus 268, and set the microphone 266 and two-way audio transceiver 380 to sleep modes to conserve the battery.

The multimedia application server 142 can also send a control message to the second set-top box device 124, requesting that the set-top box device send a variety of RF-based control signals to the remote control device 128. For example, one control signal can cause the remote control device 128 to play a short audio file stored on the digital audio storage 384 through the speaker 274. This feature can enable the user to locate the remote control device 128 if it is missing. Another control signal can cause the remote control device 128 to turn off the LED annulus 268 and to end transmission of the audio input. The multimedia application server 142 can also send a “play list” to the remote control device 128 via the second set-top box device 124. The play list can contain a set of channel numbers, which can be stored on the remote control device 128. This feature can be used to select a number of “favorite” broadcast channels by scrolling the list stored on the remote control device 128 via the LED display 386.

Also, the second set-top box device 124 can automatically scan the RF band over which the remote control device 128 is operating, such as two and two-fifths GHz. If there is any RF interference from other RF devices in a surrounding area, the second set-top box device 124 can automatically choose an RF channel with less interference and then send a control signal to the remote control device 128. The control signal can request that the remote control device re-synchronize the signal band with the set-top box device 124.

The remote control device 128 can be used to transmit a voice command to the second set-top box device 124. FIG. 4 shows a flow diagram of a method 400 for outputting a voice command to the set-top box device. At block 402, an audio input is received at a remote control device. The audio input is stored in a digital audio storage device at block 404. At block 406, determination is made whether a talk button is pressed and held. If the talk button is not pressed, then a determination is made whether a specific amount of time passes at block 408. The specific amount of time is measured from the first audio input received. At block 410, if the specific amount of time lapses, then the audio input stored in the digital audio storage device is erased. An additional audio input is received at block 412 and the flow diagram continues at block 404. If the specific amount of time has not passed, then an additional audio input is received at block 412 and the flow diagram continues at block 404.

If the talk button is pressed, then an LED annulus is turned on at block 414. At block 416, the audio input is recorded. A determination is made whether the talk button is released at block 420. If the talk button is not released, an additional audio input is received at block 418 and the flow diagram continues at block 416. At block 422, if the talk button is released, the LED annulus is turned off. Additional audio input is received at block 424. At block 426, a determination is made whether a volume of the speech received at the microphone is below a specific level. If the volume of speech is not below the specific level, then the audio input is continually received at block 424. If the volume of speech is below the specific level, then the audio input is outputted as a voice command at block 428. The voice command can be outputted to a set-top box device to perform a function associated with the voice command.

The remote control device 128 can also be used to transmit a control parameter, for varying an amplification of a voice command signal, to the set-top box. FIG. 5 shows a flow diagram of a method 500 for varying the amplification of the voice command signal from the remote control device. At block 502, an indication that a talk button has been pressed is received. An audio input is received at block 504. At block 506, an optical beam is transmitted. A reflection of the optical beam is received at block 508. At block 510, a distance to a user is determined based on the reflection of the optical beam received. A determination is made whether the distance to the user is less than a first specific amount at block 512. If the distance is less than the specific amount, then a first control signal requesting a decrease in the amplification of the voice command signal is sent to the set-top box device at block 514. If the distance is not less than the first specific amount, then a determination is made whether the distance is less than a second specific amount at block 516. If the distance is less than the second specific amount, then a second control signal requesting no change in the amplification of the voice command signal sent to the set-top box device at block 518. If the distance is not less than the second specific level, then a third control signal requesting an increase in the amplification of the voice command signal is sent to the set-top box device at block 520.
